A's relievers Blake Treinen and Lou Trivino both will miss the rest of the season with injuries, Oakland manager Bob Melvin told reporters Tuesday night.
An MRI revealed a stress reaction in Treinen's back, while Trivino has a cracked rib after suffering a fall while he was away from the team.
"It's hard," Melvin said. "It's hard for everybody. We feel that. These guys are not only big on the field for us, but also in the clubhouse. But you know, over the course of the season, things have to be done a little bit differently and we were able to pick up the slack for what have been some injuries and tough years for both of those guys."
It's a rough ending to a brutal season for the right-handers, both of whom were tremendous last year. Treinen, 31, went 6-5 with a 4.91 ERA, the worst of his career, after making the All-Star Game last season and finishing with a 0.78 ERA in 80 1/3 innings.
Trivino, 27, has been even worse this season with a 4-6 record and 5.25 ERA. Last year as a rookie, he went 8-3 with a 2.92 ERA.
Fortunately, the A's have amassed some quality depth in the bullpen, with youngsters Jesús Luzardo, A.J. Puk, and J.B. Wendelken joining All-Star closer Liam Hendriks and the always-reliable Yusmeiro Petit. Oakland also recently moved starter Chris Bassitt to the pen, where he has been impressive through two scoreless outings -- striking out seven in four innings.

As for Treinen and Trivino, the A's will have to hope that this year was an aberration and that both find a way to return to last season's form.
"My guess is they'll be back doing their thing again next year and healthy again," Melvin said. "They're both really talented guys."
